Progress on the cheap Hexapod (under £30 -or $50 US)

Britannicus

Progress update on the progress with building a cheap hex walker for under £30. I've posted the video before, but A couple of people have asked me for an upadte and more details over how it is put together. So here goes !

I've attached a PDF of my original design to this posting.

You don't have to be too precise about the dimensions, this is just what I scrounged together. I guestimate you'll need 20 hours, a drill, some 2 part glue, a jigsaw (with an aluminum cutting blade),a few screwdriver, a junior hacksaw.and some pliers. I'm happy to answer any questions

the walker before I mounted the battery underneath -this meant a minor modification but significanlty improved balance, (see the video)

raw materials -




from local DIY store -

• 8mm strip
• "L" angle aluminium 8mm X 8mm
• "U" aluminium strip - basically this is 3 sides of a box section 8mm a side
• "L" angle aluminium strip 2cmX1cm (used to mount pivot screws onto the servos)

I found all these in the worktop edges section in meter long sections which will be more than enough !





on line from CPC - but almost anywhere :

• countersunk M3 machine screws X12mm
• pan head M3 macine screws X 12 mm
• m3 nuts
• m3 nylock nuts
• IR detector (photodiode unit)
• piezo buzzer

from my RC kit supplier - 3 X 9g servos (these cost £3.99 each)





Scrounged from elsewhere

• Old TV remote to use as a controller
• 2mm sheet of aluminium (you could use plexiglass, plywood, anything really!)
• BOE with BS 2 stamp
• 220 ohm resistor and a few jumper wires
• 3.5mm barrel plug
• 2 plastic spacers (mine are circular plastic , but anything the right thickness with a 3mm hole will do)

Here's the video of the first version working - since that time, I've made a couple of cosmetic changes which are in the instructions
